AI Technical Summary
Technical Problem
Existing compound microbial agents have uneven efficiency in degrading lignocellulose, making it difficult to adapt to substrates of different sources and proportions, and traditional single-microbial methods are inefficient.
Method used
A compound microbial agent consisting of Staphylococcus warneri LH-403, Trichoderma longibrachiatum, and Bacillus thuringiensis LMU-81 was used to enhance the activity of cellulase and ligninase by adjusting the number of colonies and mixing them in culture.
Benefits of technology
It achieved efficient degradation of natural lignocellulose such as sugarcane bagasse, exhibiting broad substrate adaptability and stable degradation performance, and improved lignocellulase activity and degradation rate.
